Disclosed herein is a phosphorus compound represented by Formula 1: 

Phosphorus compound, method of preparing the same and flame retardant thermoplastic resin composition including the same

A polycarbonate resin composition comprises: about 30 to about 99% by weight of a polycarbonate resin (A); and about 1 to about 70% by weight of a rubber modified aromatic vinyl based copolymer resin (B); and about 0.1 to about 40 parts by weight of a phosphorous compound (C) including a phosphate compound (C1) and a phosphonate compound (C2), per 100 parts by weight of a base resin including (A) and (B). The polycarbonate resin composition can have excellent flame retardancy and improved heat resistance by using a combination of at least two different phosphorous compounds.

Polycarbonate resin composition having good flame retardancy

A non-halogen flameproof polycarbonate resin composition of the present invention comprises (A) about 30 to about 100% by weight of a polycarbonate resin, (B) about 0 to about 70% by weight of a rubber modified aromatic vinyl resin, and (C) about 0.5 to about 30 parts by weight of a phosphorus compound represented by the following Chemical Formula (I) or a combination thereof, based on about 100 parts by weight of the base resin including (A) and (B). The present invention can provide a polycarbonate resin composition which can have excellent flame retardancy and which can be environmentally friendly.  wherein Rand Rare each independently Cto Calkyl, Cto Ccycloalkyl or phenyl.
